Bigfoot: Real Monster or Urban Legend?

In virtually every corner of the world someone has reported seeing huge, hairy creatures that walk upright like a man but flee at the first hint of discovery. Enormous footprints found, some say planted, by witnesses here in the United States, have given these Monsters the name Bigfoot. In Tibet they are called Yeti, Native Americans call them Sasquatch, but by whatever name they are a terrifying presence to those who see them. Could there be a race of giant monsters that has survived for thousands of years, unknown and unidentified? Some claim to have photographed, even filmed them. Could all of the thousands of footprints and sightings be fake? Will you be able to believe your own eyes?
